FROM PACKAGING TO EXPLANATION

Three small steps.
A little less guesswork.

01

Show Soi the label

Photograph the full ingredient list, choose an existing photo or paste text you’ve copied.

02

See what was identified

Each additive has a name, a code and an attention level. If a photo is unclear, Soi asks you to try again without using a scan.

03

Read more, then decide

Open each additive to learn more. Revisit your history, check the original label and make your own choice.

Soi explains E330, including its functions and the limits of the assessment

READ MORE. UNDERSTAND MORE.

What is “E330”?

A name.
A function.
A source you can check.

Soi connects E numbers with explanations of their functions, scoring and what the available data does not establish.

The score only covers additives.

It does not account for sugar, salt, fat, additive concentrations or how much you eat. A high score does not mean a product is suitable for everyone.

BEFORE YOUR NEXT SHOP

You might be wondering.

Does a high score mean a food is healthy?

No. The score summarises additive classifications from the bundled data. It does not assess overall nutrition, concentrations or serving sizes. Soi is for information only, not a substitute for medical advice.

Can Soi tell me whether a product is suitable for my allergy?

No. Read the full ingredients and allergy warnings on the packaging, and ask the manufacturer or a qualified professional when needed. A substance missing from Soi’s results does not prove it is absent.

Is there a full assessment for every additive?

Not yet. Some entries lack Vietnamese names or intake assessments. Grey means the table has no assessment; it is not a conclusion that the additive is safe or harmful. Check each substance’s sources and assessment year.

Which iPhones can use Soi?

iPhones running iOS 26 or later. Apple Intelligence is not required. Photo recognition and database lookups work offline; purchases, restores and external sources need a connection. The interface supports English and Vietnamese, following your iPhone’s app language.
